In case you have services that are charged depending on the hours spent, you should create an hourly product.
Choose whether all hours, regular hours or extra hours are considered. Total hours take into account all hours spent.
Extra hours are taken from tasks with the 'Extra work' tag.
Topic selection
For hourly pricing, an additional parameter can be set to consider only hours related to a selected topic. When the topic is used on the task, the time from those tasks is taken into account.
Minimum time
Choosing the minimum time that is always billed for a given product is also possible. For example, you always want to charge for at least 1 hour, even if no time or only 5 minutes has been tracked.
If it is known for some service that it should be invoiced when the work is finished, select so on the product.
Sum all matching rows - if this setting is on, the prices of all applicable ranges will be summed. If it is not turned on, the range in which the value falls is applied when pricing.
It is also possible to create more pricing periods, so that when the date arrives, the new prices are automatically used in the calculation.
